Travel limiter for a dynamically pivoting multiple roller-brush spray

Abstract

A fluid applicator for surfaces combining a spray-gun and dynamically displacable roller-brushes with a moveable travel limiter selectively adjusts the maximum rotational displacement of the roller-brushes to prevent the same traveling across the path of a fluid spray being emitted from the spray-gun. The angle of a fluid stream exiting the nozzle is allowed to vary with respect to the longitudinal axis of the roller-brushes to more accurately control over-spray, especially with surfaces in close proximity with one another.

I claim: 
     
       1. An applicator for applying fluid to a surface comprising, a spray-gun having a nozzle defining a flow path across which said fluid will travel;   a frame having a first and second end;   a connecting means, attached to said first end, for connecting said frame proximate to said nozzle;   a pair of spaced-apart roller-brush members, defining a target plane therebetween;   a cross-member pivotally connected to said second end, defining a pivot point, with each of said pair of spaced-apart roller-brush members rotatably attached to opposite ends of said cross-member; and   means, connected to said frame, for selectively adjusting a maximum rotational movement of said cross-member, whereby said roller-brush members are prevented from entering said flow path.   
     
     
       2. The applicator as recited in claim 1 wherein said cross-member traverses an arcuate path, with said adjusting means including a detent mounted to said frame, said detent being spaced-apart from said pivot point a distance, said detent being slidably engaged with said frame and extending into said arcuate path, with said maximum rotational movement being proportional to said distance. 
     
     
       3. The applicator as recited in claim 2 wherein said detent includes a locking mechanism to selectively prohibit movement between said frame and said detent, thereby fixing said distance. 
     
     
       4. The applicator as recited in claim 1 wherein said frame comprises of a rod including first, second and third portions which extend parallel to a common plane, said first portion extending from said first end, terminating in said third portion and forming a first oblique angle therewith, with said third portion extending from said first portion, terminating in said second portion and forming a second oblique angle therewith, with both said pivot point and said adjusting means being located on said second portion. 
     
     
       5. The applicator as recited in claim 1 wherein a pair of shafts are perpendicularly disposed on each of said opposite ends of said cross member, said roller-brush members being disposed on said shafts, said cross-member having an adjustable length to vary a distance said shafts are disposed from said pivot point. 
     
     
       6. A fluid applicator comprising, a manifold body, including a fluid inlet and a fluid outlet and means for selectively placing said inlet and outlet in flow communication;   means, in fluid communication with said inlet, for remotely storing a fluid, with respect to said inlet, and transporting said fluid to said inlet under pressure;   a nozzle in fluid communication with said outlet, defining a flow path over which said fluid travels;   an elongated wand, extending along a longitudinal axis, between said nozzle and said outlet to remotely dispose said nozzle with respect to said manifold body;   an assembly removably attachable to said wand including a frame having a first and second end, a connecting means, attached to said first end, for attaching said frame to said wand, a cross-member pivotally connected to said second end, defining a pivot point, and a pair of spaced-apart roller-brush members rotatably attached to opposite ends of said cross-member; and   means, connected to said frame, for selectively adjusting a maximum rotational movement of said cross-member, whereby said roller-brush members are prevented from entering said flow path.   
     
     
       7. The applicator as recited in claim 6 wherein said connecting means includes a clamp attached to selectively squeeze said wand, thereby allowing a distance between said roller-brush members and said nozzle to be varied. 
     
     
       8. The applicator as recited in claim 6 further including a handle attached to said wand, said handle including a grip portion, which extends along a centerline and a clamping device adapted to selectively squeeze said wand, thereby allowing said handle to be affixed to said wand at different positions along said longitudinal axis. 
     
     
       9. The applicator as recited in claim 8 wherein said grip portion is pivotally attached to said clamp means to rotate 360°. 
     
     
       10. The applicator as recited in claim 6 wherein said cross-member traverses an arcuate path, with said adjusting means including a detent mounted to said frame, spaced-apart from said pivot point a distance, said detent being slidably engaged with said frame and extending into said arcuate path, with said maximum rotational movement being proportional to said distance. 
     
     
       11. The applicator as recited in claim 10 wherein said detent includes a locking mechanism to selectively prohibit movement between said frame and said detent, thereby fixing said distance. 
     
     
       12. The applicator as recited in claim 6 wherein said wand includes an outer shielding having opposed termini and a flexible hose disposed therebetween. 
     
     
       13. The applicator as recited in claim 12 wherein said outer shielding includes a coupler disposed therein at each termini, with opposed ends of said flexible hose being affixed attached to one of the couplers.
